10 Second Rule is an expansion from the 5 Second Rule due usually for being too drunk! By the time the food has been dropped, your mind figuring out it has been dropped and finally realising you DO have to bend down retrieve the food it's still fine to just give it a rub off and continue to eat it. (If you are drunk, so are germs, therefore it's going to take them longer to get to the food.)

When you drop food on the floor but still want to eat it.
You have to pick the food up off the ground before 10 seconds. If it has went past the 5 second you must declare that it's went to the 10 second rule.
